thank you, for everyone searching the archive:
	"set arm abi AAPCS" (instead of default APCS)
fixed it.

not yet sure what it is, but:
root@OpenWrt:/nfs/tmp# ldd ./hello
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x4000e000)
        libc.so.0 => /lib/libc.so.0 (0x40020000)
        libc.so.0 => /lib/libc.so.0 (0x40083000)
        ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x40000000)

he furthermore now claims:
warning: no loadable sections found in added symbol-file
/data/harald/root/lib/libgcc_s.so.1
warning: no loadable sections found in added symbol-file
/data/harald/root/lib/libc.so.0

I have to dig a little bit deeper, most likely OpenWRT is guilty here,
unless gdb does something really weird.

Thanks a lot
	Harald
